Solid Phase Spectrophotometric Determination Of Cobalt By Xylenol Orange
A simple and sensitive solid phase spectrophotometric method for the determination of cobalt is proposed based on the reaction between cobalt and xylenol orange (XO). The reaction product is fixed on the anionic exchanger resin sephadex QAE A-25 at pH= 5. The optical absorbance of the anionic gel like resin, packed in a 1.00 mm cell is directly measured at 588.0 nm. The linear range of calibrat...
متن کاملSimultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares
A partial least squares (PLS) calibration model was developed for the simultaneous spectrophotometricdetermination of Pb (ΙΙ), Cu (ΙΙ) and Ni (ΙΙ) using xylenol orange as a chromogenic reagent. The parameterscontrolling behavior of the system were investigated and optimum conditions were selected. The calibrationgraphs were linear in the ranges of 0.0–9.091, 0.0–2.719 and 0.0–2.381 ppm for lead...
متن کاملSpectrophotometric Determination of Nickel with Chlorophosphonazo-III
The optimum conditions for spectrophotometric method for the determination of Ni with chlorophosphonazo-III (CPA-III) were established and the nickel content in water samples has been successfully determined. In a pH 5.5 acetic acid-sodium acetate buffer medium, CPA-III and Ni formed a 1:3 green blue complex and the maximum absorption wavelength of the complex is at 620 nm. Ni content in a rang...
